A cool video from a national park in Alaska shows what appears to be some kind of flying saucer hovering over water, but the 'alien craft' is actually an optical illusion. The wondrous scene recently unfolded at Glacier Bay National Park and Preserve, which posted a video (which can be seen below) of the odd moment on their Facebook page. In the footage, an odd object that somewhat resembles a hat can be seen silently floating in the sky over the bay.
